I know how it is to live in places where you have little choice as to what martial to study since only one style is available. I trained in many karate styles over my years in the Navy because they were the only martial arts available where I was stationed. Some had techniques and philosophies that I agreed with, some did not. Either way, while I trained at the schools, I did things as they did them and learned from it.
Switching styles is similar to moving into a new house. At the new house you bump into things, moving around the house seems awkward, and sometimes you wish you were back in the old house. However, after a while you get settled in and the new house turns out to be just as good, if not better, than the old house.
In your situation, whether Taekwondo is better or worse than another martial art doesn’t really matter since Taekwondo is your only choice. Even if you do not particularly care for Taekwondo, something is better than nothing.
